;; Standard build procedure for Perl packages using the "makefile
;; maker"---i.e., "perl Makefile.PL". This is implemented as an extension of
-;; `gnu-build-system'.
+;; `gnu-build-system'. Cross-compilation is supported for some simple Perl
+;; packages, but not for any Perl packages that do things like XS (Perl's FFI),
+;; which makes C-style shared libraries, as it is currently not known how to
+;; tell Perl to properly cross-compile.
